Solving some of the scalability problems at Booking.com

Booking.com uses Sereal in many applications. One of the biggest use case though is the events pipeline. It was built to delivery messages (events) from generation point to various processors in near real-time fashion. These days it servers billions of messages per day.

One of our processors recently faced scalability issues due to growth of the volume of delivered events.

In this talk I would like to share what problem we had, how we addressed it and which new features of Sereal helped us.
